The sound transmission across two coupled cavities along a rectangular duct in the presence of a low Mach number flow is examined experimentally in the present study. An effort is also made for a deeper understanding of how the flow, excitation sound...

The sound propagation across a sound leaking section along an infinite rectangular duct-like structure near to the lower order duct eigenfrequencies is investigated numerically in the present study. The sound leakage is achieved by finite length rect... Read More about On sound propagation along an infinite rectangular duct-like structure with a finite slot opening and its modelling.

Device called”enhanced acoustic balcony” is installed in a public housing development in Hong Kong. It is intended to help mitigate the impact of traffic noise on the residents. This balcony is basically an enlarged form of a plenum window allowing a... Read More about Noise reduction of enhanced acoustic balconies on a high-rise building block.
